Complaint account TELKOM

Good day I want to complain about the bad service (if any service at all) by Telkom. In November 2018 we cancel our ASDL (Internet) line as it was more out of order that of use. Telkom kept on billing me until I phoned them again in April 2019 and the lady at the call centre immediately corrected my account and said the credit will show on my account in June 2019, which in fact was so and my account showed a credit balance. When I look at my account now in October 2019 I saw that Telkom was STILL charging me for the Internet - DSL Faster and Home Uncapped. For the past two (2) weeks I am battling to sort my account by phoning the call centre but with no luck. I got a guy Keegan and he sent me all my accounts since March 2019 of which I did a recon. When I spoke to him I specifically ask him if I can email him back with my recon and he said yes I can. After I done my recon I send it to him but to this day he has not come back to me as his email was a NO REPLY email address. When I phoned the call centre to speak to this guy, Keegan, he was not available and any one can "HELP" me. Yesterday 27 October 2019 I went to the Telkom shop in Key West to try and sort my account, because my line is suspended and I need the landline for my 91 year old mother to call if there is an emergency. All they could tell me at the shop is that I must phone the call centre they do not do account queries at the shop. The lady at the shop did log a call to the Telkom centre to phone me back but it was very noisy in the shop as the consultants talk so loud that I could not hear on the phone. Eventually I got a reference number from the guy on the phone. Why can they not sort the problem as it is their mistake charging me for services I DO NOT have!!!!!! When I phoned them this morning again, the guy Hlonshane, told me that he can see that I do not have the service of Internet and a credit will be passed on my account. He also said that they will send me a SMS with a reference number, which I did not yet received. I also told him that I want my line fixed by 17h00 today 28 October 2019, as it is somebody not doing their job correctly.
